19 hp and 20 trq were total gains from CAMS, Now According to the shop I went to they said my auto trans shaved off at least 15-20hp from what a manual tranny would have produced. Never knew auto tranny's made that much difference. Ill start data logging in a few days cause my cable never came in yet. Apparently Uprev had a pretty big backorder on them. He sent it 2 days ago should be here tomorrow. NOTE: All dyno numbers were based on 91 octane and 3rd gear pulls.

I looked into it a while ago using a NX sender and there is no real point to as when it kicks in its was great power where I drove my truck. it might help in track use but for the time investment not much gain if any. your best gains now will be to lose the K&N and go a closed box intake

Ya I was thinking about that, but Ill probably get a new filter and enclose the heat shield that K&N gave me and also increasing the size of my exhaust from my 2.25 to 2.50 or2.75 cause I feel there is to much back pressure.

hmm not sure about that set up i would run 2.25 off highflow cats to an X pipe to a 2.25 in and out muffler and out.

also is there a good drive shaft shop around you. look into getting a 1 piece driveshaft, might be able to cut some weight out there. also lower gears will help

I just got my whole rear fixed and Im not 100% sure but Im almost positive they gave me the manual 3:73 rear instead of the auto 3:36 gears...... I dunno about any good shops around here but ill look into a road trip. Im gonna do testing with out the tailgate to see what/and how much of a difference is. And if im feeling really stupid ill take off the hood lol

I think your dual 2.25" into to 3" is just fine. The only week point I see is your stock cat tubing. It looked like it narrows down to about 1.75" to me, and is the main reason I changed my cats. You remember I have all dual 2.25" tubing on my truck and I dont think it's hurting me at all. According to calculators I checked, that size should be easily safe to handle 300whp on a motor with our displacement.

Well, I honestly think its the primary cats surrounding tubing and angles that do the most harm. But hi-flow cats are an extra bonus. I have everything going as straight as possible and using all 2.25" tubing and all mandrel bends.

Very soon, maybe tomorrow is the weather holds out. I've has alot of rain lately closing the tracks around me. Also, remember every dyno reads different. I would say your shop is pretty conservative. With the times you are running, I wouldn't worry much about your HP numbers being so-so. Your truck is putting great power AND very important, your getting it to the pavement great too. Again your times and little wheel spin is the real proof.
